Modulation

Exposure setup

Animals were placed in a ventilated Plexiglas carousel consisting of ten circularly arranged tubes with their heads as close as possible to the central antenna. The GSM phone was controlled by a GSMRF Test Set, and a conversation was simulated.

Additional parameter details

The precision of the SAR assessment has been estimated to be better than ± 30%.

Measurement and calculation details

For the experimental dosimetry the phone was replaced by a signal synthesizer. The efficiency of the system was determined by computer simulation and validated with thermoprobes inserted into the brains of rat cadavers. The variation of the brain-averaged SAR levels due to size and movement was assessed to be less than ± 16%. Details can be found in the reference article.
